What element contributes to the richness of the NY style cheesecake?

The richness of NY style cheesecake primarily comes from the use of cream cheese. This ingredient is known for its smooth, creamy texture and rich flavor, which forms the base of the cheesecake. Cream cheese has a high fat content, which not only adds to the overall richness but also provides a dense and luxurious mouthfeel that is characteristic of New York style cheesecake. This texture and taste are what differentiate it from other styles of cheesecake, making cream cheese essential for achieving that signature richness.

Egg yolks contribute to the structure and emulsification of the cheesecake, but they do not provide the same level of creaminess. Milk is used in various desserts but does not significantly enhance the richness in the same way that cream cheese does. Sugar, while essential for sweetness, does not contribute to the textural richness that cream cheese provides. In summary, cream cheese is the key ingredient that defines the rich and creamy nature of NY style cheesecake.
